contemplated applying that principle, so as todistmguish 1t 'fro1 nother inventions.

lily invention relates to machines for spreading manure,

'lrjljachines now upon the market designed for the use indicated arecharacterized by extreme complexitygin their operation and by aconsequent great liability to get out of order.

The olnects of my lnvention are to pro-- ride a machine for the purposeunder consideration which will be extremely simple in its structure andin. its methods of operation, and which will hence be little liable toneed repair,

Other objects of the invention are to make the draft oi? the machineeasier, and to prolent the driving mechanism from dirt and mud.

To the accomplislnnent of these and related ends, said invention, then,consists of the means hereinafter fully? described and particularlypointed'outin the claims.

The annexed drawings endthe roilowing description set forth in detailcertain 1nech-,

unism embodying the invention, such disclosed meens constituting,however, but one "various mechanical forms in which the principle of theinvention rusty housed. 'l'n'said annexed drawings :lf igure 1 a sideelevation of a machine embodying my invention, and Fig. 2 is a brokenplan thereof, with certain parts removed.

The machine in which my invention. here embodied comprises the ordinaryloadcarrying box 1 mounted upon the usual wheels 2, and the whole isprovided with a suitable seat and draft tongue. Disposed transverselyacross the front of the box 1 is it beater which comprises a rotatubleshaft provided with a plurality of rudialpins and having secured theretoat one end a sprocket. A. continuous apron 4t terms the bottom of thebox]; the apron 4t rnfls over two transverse rotatable shafts 5 disposedrespectively at the front and rear of the box end provided withsprockets 6 and 7 which able through suitable connecting rods areengaged by chains carriedby the apron: A plurality of small rollers 8are secured along the bottom of the box and. serve to support the apron4 intermediate the shafts 5, Two sprockets 9 and 12, formed integrallywith each other, are mounted loosely uon the rear axle 15. Throughintermediate sprockets 10 and 11, mounted on shafts journnled in themachine frame, the sprocket 9, by connecting chains, drives the forwardshaft The other sprocket 12 of the two integral sprockets, byintermediate sprockets 13 and 1.7, drives the beater 3, The sprockets 9and 12 are loosely mounted on the axle 15, but are adapted to beconnected to rotate with the axle by a. clutch 1+1- operoperator. 1 l yin operetion the wagon is loaded with manure and then pol ed forward,the clutch being in disc position. El is-in, then, the opera tint we theclutch into engagement, theintegrai s; ockets, through theirintermediate chain and sprocket eounections, will move the apron whichforms the bottom of the box forwardly, mind at the same time will rotatethe beater forwardly. The intermediate chain. and sprocket connectionsthrough which the apron driven comprise successively larger sprockets sothat the whole serves ultimately to drive the apron at a speed muchslower than that of the driving axle. 'lhe beater on the other hand isdriven at a comparatively high rate of speed because intermediatedriving sprockets e successively smaller. 1, machine moves along, then,the load is slowly moved forwardly, and as it reaches the front end ofthe boxit is loosened and scattered by the beater.

The many advantages attained. in. the machine as d scribed, should beobvious, in the first place inacliines'oit this kind here-- totore onthe market are Characterized by the fact thutthe movable bottom movesrearwardly and the heater is located at the rear end oil the bout.Therefore, the load becomes continually lighter the trout of the box,tor as it diminishes, the load is 7 moving; rearwardly, Compared withthe front end of the box, then, the rear end is becoming constantlyheavier the load is discharged, and it is well known that this serves tomake the dral t heavier and harder it obviate this serious detectentirely by providing a forwardly moving bottom and e by the ltlllbeater disposed atthe front of the box. The

load, therefore, is lightened gradually from the rear toward the front,and the draft becomes constantly easier. I have also cast aside all-ofthe involved driving mechanism for. the apron andthe beater which isusually found in machines of this type, and have provided drivingmechanism consisting simply of chain and sprocketconnections.Furthermore, the driving sprockets, which drive the apron and thebeater, are formed integrally and can be disconnected from the drlvingaxle by disenga ement of a singleclutch; conse uently the c utch may bethrown out and t 0 whole load drawn along as .simply a loaded wagonwith: no internal mechanism in operation at all.

' Finally it is to be noted that I employ a tected from seepage of'dirtand mud from continuous apron for forming the bottom of the box, and theupper fold of the a ron extends above the drivlng and interme iateConsequently the driving the load, or from dirt thrown up from be-,

' low.

It will, therefore, be seen that I have provided a machine characterizedby extreme simplicity, for it comprises only a few simple arts and eventhese few parts are so arranged that they are subjected to nounnecessary operation, and are effectually protectedfrom dirt anddestructivewear. At

the same time I have so disposed and arranged the operative mechanismthat the machine is-more easily drawn as the load is scattered;

Other modes of applying the principle of my-invention' may be employedinstead of the one explained, change being made as regards the mechanismherein disclosed, provided the means stated by any of the followingclaims or the equivalent of such stated means be employed. I

. I therefore particularly point out and 'dis tinctly claim as myinvention 1.
